MycoGrow™ Soluble is similar to Plant Success™ Tabs but is more concentrated, containing more spores and more species, plus other beneficial organisms. Consisting of powdered spore mass rather than tablets, MycoGrow™ Soluble is great for adding to rooting media or commercial potting soils. An ounce is sufficient to treat 125–250 plants covering approximately 250 square feet. Sold in 1 pound increments.

Note: cannot be shipped to Hawaii.
